Help!

I'm going to ask a dumb question, not to insult you but because I've made some silly mistakes myself in the past.

Are you sure you're adjusting the floats to carbs 1 & 2? And you have the carb in the right orientation when you make the adjustment?

When you made the initial setting you used the 1.125" height?

Yep, that is one reason I number the carbs, the float covers, everything gets numbered as its location, and put in same place.

How pliable is the little tab that is bent to adjust the height of the float? If it's too weak it might be just bending back after you adjust it. Have you remeasured after you've taken it apart after checking the wet level? If so, were they the same as when you assembled?

Did you do the tests i suggested?

The height was the same after I reassembled, checked height, and took apart again. The tab is stiff and when I adjust, i usually need to push on tab several times before I adjust it.

How do you know if the floats are moving freely with the covers on? Are you testing float level with an external tank? Carbs shouldn't even go back on the bike until floats are checked on the bench. Blow into each carb vent...shouldn't hold vacuum. Turn upside down and do the same.


So I went out there with carbs still on bike, and blew in vent tubes. Gas came out of one of the jets and almost got me in the eye. I tried all four and got same result.

How would I test with external tank? I dont understand what to do. I dry check each carb with calipers. Is there a way to wet check on bench? If there is, it should have been posted as a sticky or added to the carb section.

Carbs are apart now as I wanted to post photos of carbs. I can reassemble and try vent tubes upside down.

Sorry about that. I assumed carbs were off. Yep, auxiilarry tank is what I use from Dennis Kirk. Should've huh? You forget, we do help sections for free and it isn't our "job".

 

[motomick76]

Sorry, I get frustrated, and I got my Harley neighbors riding by too, looking in and driving me nuts.

Now, I have the carbs apart and on my bench. Everything is laid out like the previous pictures. What do I need to do with the vent tubes? And from what I can tell, there is a process to check the float levels wet on the bench with each carb individually?

 

[maleko89]

No problem.

Since you don't have an external tank just hook each carb to fuel line from the fuel pump. Check this pick for an idea. Before you do that, turn it upside down and blow in fuel inlet...not vent. If upside down it should hold vacuum. Right side up, it should not.

What gives with this forum? I PM Sean last night about some of my problems. I have spent all week and weekend working on this bike, in my garage. Is somebody gonna be able to help me, or do i need to find other sources? There is not much riding time in Minnesota, and it frustrates me to see it go to waste.

Just be honest.

It's great that you apoligized. You'll get the help you need here. I use the casting circle just under the v in the floats. This gets me very close tot 17mm. I've also, like mentioned had to bend the float pin to keep the floats centered and not hanging up. I only got it perfect on the first try once.

10-4 thank you. I will try the vacuum trick tomorrow as I would like the carbs to air out.

 

[maleko89]

Notice in the pic you don't need the fuel level gauge. Just use the drain hose and lower until fuel level is even with end of drain hose.

I am using this forum and writing a post and any post as my last resort. I have spent hours and bookmarked may vmax websites offering help, and reading what they have done to fix their problems. I realize everybody has lives, and so do I. I do not want to spend every night in my garage or searching on the forums, but I am very resourceful and try everything I know to do before I ask for help.

My first post was who can I call for help. I am willing to pay them if need be, or call them during normal working hours. But I want to understand the problem so I learn. I said 'What gives with the forum' that because I wanted the question answered, WHO CAN I CALL, or IM I don't care if it costs me money. The question still is unanswered.

I have done everything possible sugessted in this forum, outlaw forum, and it has helped me greatly. THANK YOU everyone that has helped me. If we ever meet up, I will gladly buy you a 'cold one'.

std354 and forum members,

Sorry if I upset anyone here, and I send my apologies.

If you feel that the floats are a problem quit wasting time by putting the carbs back together till you know they are right.

If you have two that are not changing no matter what you do, why not open up a carb that seems right and start swapping parts one at a time and keep checking wet levels on the bench to see if you can get it right. Rig up an external fuel source and dont put the carb halves together, leave the rack split. It will save time in this process.

I cant think of anything that would keep the bowl from filling up? A bad needle, seat, or leaky floats are going to give too much fuel. Maybe an internal blockage or the rubber lines that feed the carbs. If it was a filter issue i would think all four would be affected, not just two. Are you getting proper flow from the fuel inlet to the bowl? Are the vent lines clear on the offending carbs? Kinda hard for the fuel to go into the bowl if the bowl doesnt vent. You can teat this without pulling the rack, just pull the hoses while doing a wet check.

Maybe this is what I should try. I will build bench setup and swap parts from 1 into 3 and see if I find a difference and check levels.

std354 and forum members,

I for one was not the least bit upset by your earlier post asking where everyone was. I have been frustrated myself and sometimes have said or done the wrong thing in my frustration. Part of the human condition in my opinion. This is a great forum and I've learned a ton from reading the posts and how-to-guides on it. I hope that you work out your carb issues. Another thing to look for, see if there are any other members in your general area that might be able to lend a helping hand.

I'll assume you have a shop manual but there is a great DVD put together by a Vmax master in Michigan named Damon Ferriaolo. His video walks you through a detailed tear down and rebuild. It shows the float set procedure and well worth the money for all the knowledge it contains. PS, he has an engine Video too! Check them out.
By the way, frustration motivates me. I see how your statement sounded like we should be at your beck and call but surely all of have been in your position and had to "Vent" a little. Keep at it Moto. You will get it.


When in doubt...Gas it !!!

I tried doing a Google search and could not find anything. Where else could I find these videos?

I also want to share my experiences with everyone in adjusting the float levels. It is critical that they are right. But I kept having trouble with two carbs and the level. They 'dry measurement' was all the same on all four, and I rechecked three times with dial calipers. The problem I found out is you can have the correct dry adjustment, but that does not mean the 'wet' adjustment will be at 16mm. Two of the carbs I had trouble with the wet level are different than the other carbs when adjusted to the dry level.

So if you were to take them apart, and measure the 'dry' level, they would be way off. But when you 'wet' check the carbs, they are all right on at 16mm. And I could tell which carbs I was having trouble with because of the plug color (brand new) and the way the bike ran between 4-5k. I tossed the 'dry' measurement and concentrated on the 'wet' and now my bike runs great.

I also want to give a big 'THANK YOU' to Sean unk:. I emailed him and he went way over and beyond in helping me with my questions. I will definitely be looking him up later for some parts for my machine this winter.

Thanks everyone for your help,
